First, Install Additional Capacity
Install the additional physical capacity (hot-swap disk drive modules) into the
internal hot-swap mass storage cage or into the external enclosure. The cage or
enclosure must already be connected to the integrated HP NetRAID controller or
HP NetRAID Series adapter controlling the logical drive that you want to expand.
Second, Reconstruct to Add Capacity
1. Load the HP NetRAID Config utility (megamgr.nlm module) under
NetWare.
2. Select Advanced menu, then select Reconstruct Logical Drive.
3. Select the logical drive to reconstruct. The controller scans for new drives.
4. Select the drive to be added per the on-screen instructions and enter the
Reconstruct menu.
In our example, this allows you to add the drive and reconstruct the
four-drive RAID 5 array to a five-drive RAID 5 array.
Reconstruction is done in the background so there is no need to shut down
the server. When reconstruction finishes, our sample drive now has 16 GB
of available physical capacity. The original 12-GB volume VOL1 is still
intact.
The reconstruction rate is about 80 to 180 MB per minute (depending on
drive performance and system loading). Count the capacity to be
reconstructed as the number of physical drives participating in the
reconstruction multiplied by drive capacity.
Third, Make the Added Capacity Available in NetWare 4.2
After the logical drive has been reconstructed in HP NetRAID Config, make the
added capacity available in NetWare 4.2, as follows:
1. Return to the NetWare Install module.
2. Select Volume Options.
3. Add a new segment under the NetWare partition. You can either make the
added capacity a new volume or it can be part of the original volume. If
made part of the original volume, the original volume need not be
dismounted.
In our example, the new segment size must be 4 GB or less as this is the
amount of added capacity.
4. Save your changes. If the new capacity is part of an existing volume, it is
mounted automatically (if the existing volume was already mounted). If
the new volume is separate, mount the volume. The new capacity is now
available for use.
